With thanks to Peter Crosby. I originally was going to write my own summary of what a tragedy Concur is, but the million monkey's theorem wins every time, so here is a link to a fanastic write-up from 2007 that details all the issues we have in mid-2013, except that the poor author didn't realize that not only would Concur ignore his blog, they would also take each bad feature and make it worse, then proceed to their laboratory and invent previously-unthought of bad features and add them.

There's been a lot of secondary sources quoted and written up and the media has multiplied that into a thousand articles on the 300G DDOS SpamHaus attack and what it did to cloudflare.
For a media-free viewpoint, simply go here http://cluepon.net/ras/gizmodo to see something written firsthand, by Cloudflare's network provider ( probably GTT ).
I'm not going to copy & paste, please go to the link.

So my fanbase will have noticed my site has been down lately. (Actually it's been down twice. Because of updating drupal. More on that later. ) And they might wonder, with all my inside industry information if perhaps I am not on a pastebin list somewhere or other.... perhaps a target of those evil-doers who are out to destroy all the good in networking. The legion of network villains, I think they are called. And if you did it would have SHOCKED you to know my site has been down for 3 days while I've been travelling on business - my biggest outage ever!

So it's no secret I work at F5 now.
I recently had a customer have some problem with routing, and I got to understand a little bit about the F5 ZebOs user interface, which is of course, all on the command line.
The important bit is it's perfectly valid to do a config t and just paste in your routing config. Assuming your vlans and "self-ip's" (I'll never, ever get used to saying that) match of course.
More later. Much more!
